Nobody's talking about his offense translating. I don't think it will either. Drew Miller doesn't produce points in the NHL either but that hardly means he's one dimensional. Like Miller (or Prust, or Maltby) Callahan can skate, play special teams, and is defensively responsible. So he's already miles ahead of the bozos you seem intent on comparing him to. I'm also curious to know why you'd think he's similar at all. He's not used in any way like those guys are. The only thing similar is that they'll fight once in a while. Other than that Mitch Callahan is nothing like those guys. When a coach as good as Blashill is using you on the PP, PK, and giving you top six minutes, and leaving you on the ice at the end of games you're surely a better player than some fourth line agitator...regardless of how often you do or don't score.
Actually he's used EXACTLY like those guys were used in the AHL. An aggressive forward who can shift up and down your lineup and play in any situation....in the AHL.
Those "bozos" did all that at the AHL level as well AND put up better numbers than Callahan AND were used on the PP and PK.
Which is why they're an ok comparable at that stage in their career.
